Given the infrequent need for housekeeping operations using solvents within the room, particularly over the course of a single room air change, solvent vapor concentrations should remain safely below the 1% LC50 limiting concentration at all times. Substance Inhalation LC50 1% LC50 Vapor Mass Required Minimum Number of 5 (Limiting to Bring a 13,440 cf. mL Doses to Bringthe Concentration) (380,578 L) Room to Room to the Limiting the Limiting Vapor Concentration Concentration Acetone 50.1 mg/L(rat 8 hr) 0.50 mg/L 190 g 47 76 mg/L(rat 4 hr) Ethanol 38 mg/L(rat 10 hr) 0.38 mg/L 145 g 36 39 mg/L(mouse 4 hr) 117-125 mg/L(rat 4 hr) Isopropanol 40 mg/L(rat 8 hr) 0.40 mg/L 152 g 38 53 mg/L(mouse) 72.6 mg/L(rat) 72.6 mg/L(rat 4 hr) In addition to the identified solvents, certain cleaning operations may generate hydrogen gas through the reaction of lithium metal with water.This reaction generates 1.6 L of hydrogen gas per gram of reacted lithium metal. While lithium inventories may vary significantly between the components being cleaned, anticipated inventories are on the order of 1-100 grams.As the following table indicates, significantly larger amounts of Lithium metal are required to exceed the 25% LFL limiting concentration for hydrogen gas within the room.
